Preparation and processing equipment and method for aluminum oxide grinding medium

Abstract

The invention provides preparation and processing equipment and method for an aluminum oxide grinding medium, and relates to the technical field of preparation and processing of grinding media. The preparation and processing equipment comprises a bottom plate, a supporting frame, a mold pressing device and a drying device, wherein the supporting frame is fixedly arranged on the bottom plate, the mold pressing device is arranged on the supporting frame, and the drying device is arranged below the mold pressing device. In addition, the preparation and processing equipment and method can solve the following problems that a, in the existing preparation and processing process of the aluminum oxide grinding medium, the volume density of the aluminum oxide grinding medium is unqualified, the quality of the aluminum oxide grinding medium is poor, the aluminum oxide grinding medium is prone to being broken in the using process, and therefore the equipment is damaged when a mill is used; and b, in the existing preparation and processing process of the aluminum oxide grinding medium, the product is not subjected to subsequent drying treatment in time after mold pressing, so that the aluminum oxide grinding medium is not of a regular spherical structure during forming, and the shape of the product is changed.

Description

technical field [0001] The invention relates to the technical field of preparation and processing of grinding media, and specifically proposes equipment and a method for preparing and processing alumina grinding media. Background technique [0002] Grinding medium is a metallurgical term. The energy carrier in the mill crushes the material by its own impact force and grinding force. Therefore, the quality of the grinding medium is very important. Most of the existing grinding media use glass beads, steel balls, and zirconium silicate. Beads, alumina, zirconia beads, pure zirconia, etc. Among them, alumina grinding media is the most widely used, because it has the advantages of high temperature resistance, good wear resistance, regular shape, easy classification, high grinding efficiency, and favorable price. Alumina grinding media comes in a variety of shapes, such as balls, columns and bars, with balls being the most commonly used. [0003] With the wide use of alumina gri...

AI Technical Summary

Problems solved by technology

[0004] (1) During the preparation and processing of the existing alumina grinding media, the bulk density of the alumina grinding media is unqualified, the quality of the alumina grinding media is poor, and the alumina grinding media The medium is easily broken during use, which will cause equipment damage when the mill is in use

[0005](2) During the preparation and processing of the existing alumina grinding media, the products are all molded and not followed up in time for subsequent drying treatment, so it is easy to cause alumina The grinding medium is not a regular spherical structure when it is formed, resulting in a change in the shape of the product
